A.o. Smith 100093874 Gas Control Valve Kit Lp Propane

Product Description

The A.O. SMITH 100093874 is a replacement gas control valve kit configured for LP (liquefied petroleum) propane fuel. The gas control valve regulates fuel flow and system operating functions within a propane-fired water heater, serving as a direct OEM-style replacement for the original component. Licensed plumbers and HVAC technicians install this part during service calls where the original valve has failed, drifted out of calibration, or been flagged during inspection. Its propane-specific configuration makes it the correct choice for LP installations and not interchangeable with natural gas valve assemblies.

This valve kit is intended for use in residential propane water heater applications where a factory-matched replacement is required. Because it is sold as a kit, it includes the necessary components for a complete valve replacement rather than a partial repair. Technicians working on propane water heaters should confirm the fuel type matches LP before installation, as natural gas and propane valves operate at different pressures and orifice sizes.

Key Features

• Configured specifically for LP propane fuel — not for natural gas use
• Sold as a complete kit for a full valve replacement
• OEM-style replacement designed to restore original system function
• Intended for professional installation by licensed plumbers or HVAC technicians
